- Abstract
It was studied the effect of heat stress on productive capacity at ROSS 308 female parents exposed to high temperatures during the day. The hens were reared on the floor, in intensive system. The experimental period was of 5 weeks, of which 2 weeks were high temperatures and 3 weeks were very high temperature into the house. The following parameters were monitored: egg production, egg weight, egg mass, feed intake, specific number of incubated eggs. The egg production, intake and incubated eggs were recorded daily; egg weight and egg shell thickness weekly. The productive parameters were significantly influenced by exposure to warm temperature (p=0.05). It was observed a significant decrease in egg production and feed consumption and a high percentage of cracked eggs, which can not be utilized for incubation. The number of incubated eggs was reduced by 37%.
